Back when I worked, we had a 100% results and task-based system. (I was a prof.)
This was amazing, since as long as you taught your classes, did your grading, published stuff and supervised grad students, nobody cared when or where it happened.
I got tons done by 3 pm every day, starting about 7ish.
Yes we did work 7 days a week for much of the winter, no choice.
But it balanced out in the summer, for me, because once I hit my self-imposed publishing goals, I slowed right down and rested up for fall, read for interest, etc.
Most people didn’t ever set a limit to the self-driven part of the work (research and publishing) and were constantly burnt out.
Anyway a results-based system—oh yeah, with purely competitive raises, no automatic raises, just increases based on performance—gets people working like crazy badgers, in my experience.
